When I purchased this rock from the lfs it had two visible polyps and in the last two months I've had tons of additional growth on it. It's always looked healthy except for two polyps that have these brown bubbles on it. Almost as if they were burned or agitated. It hasn't gotten any better or worse since I've had it and no other polyps have had signs of it.
It's the first polyp on the right
What do you think it is
